Abstract

A device according to the invention for closing a pivotable flap of a motor vehicle, in particular a motor-vehicle tailgate, comprises a first, hinge-bracket point of attachment for a spring on a hinge bracket of the flap; a second, bodywork point of attachment for a spring on a region which is fixed in relation to the flap; a spring, for example a tension spring or a pneumatic spring, which is arranged between the first, hinge-bracket point of attachment and the second, bodywork point of attachment; and a displacement device for the first, hinge-bracket or second, bodywork point of attachment of the spring. The displacement device can be activated by the control unit such that the first, hinge-bracket or the second, bodywork point of attachment of the spring is displaced from the starting position into a door-closing-displacement position, which can be determined by the control unit, with account being taken of the position of the motor vehicle, and in which the spring-force-opening moment, which results from the direction of action of the spring and the lever arm located at right angles thereto, is smaller than the closing flap-weight moment, in order for a closing movement of the flap to be initiated from the open flap position, and that the first, hinge-bracket or the second, bodywork point of attachment of the spring, in the event of a certain flap-pivoting position being detected, is reversed from the flap-closing displacement position into a reversing position at least a little closer to the starting position, in order for the closing energy of the flap to be reduced.

Abstract

A method according to the invention for producing a corrosion-resistant spring, in particular a compression spring for an injection pump or for a flap opening system of a motor vehicle, a tension spring, or a torsion spring, comprises the following steps: providing a spring wire made of an oil hardened and tempered, Si-CrNiV alloyed base material having a hardness of 400 - 490 HV2; winding the base material and cutting the base material to length to form a spring; grinding the spring ends of the spring; and forming an anti-corrosion layer having a thickness of 5 - 9 μm, in particular 6 - 8 µm, which extends over the circumference and the spring ends of the spring wire and which has a nitride layer and an outer oxide layer, which is introduced into the nitride layer and which has a surface hardness of 685 - 885 HV0.5, by subjecting the spring to a nitriding treatment, by post-oxidizing the spring in a salt bath, and by shot peening, in particular intermittently shot peening, the surface of the spring.

Abstract

The invention relates to an actuating device for an exhaust flap of a boost pressure controller of turbocharged internal combustion engines, in which invention the exhaust flap is arranged pivotably in an exhaust-gas line, in particular in the housing of a turbine of an exhaust-gas turbocharger, and controls the opening cross section of a bypass line which bypasses the turbine in a manner which is dependent on the compressor-side boost pressure, wherein the exhaust flap is arranged on an actuating arm which is fastened on a shaft which is mounted rotatably in the exhaust-gas line, which shaft can be adjusted outside the exhaust-gas line via an actuating lever and a control rod which is articulated thereon and via a linear actuating motor. In order to avoid oscillation-induced buzzing noise in the actuating device, it is proposed that a frictional damper (34, 44, 46) is connected into the force flow between the shaft (24) and the control rod (30), in particular for system damping in the region of the exhaust flap (18).

Abstract

The invention relates to a device (30) for closing a pivoting flap (4), in particular a tailgate of a motor vehicle, comprising a first hinge rod side connection point (16) for a force element (14) to a hinge rod (26) of the flap (4); a second body-side connection point (20) for a force element (14) on a stationary region opposite the flap (4); and a force element (14), in particular a spring element (14), such as a tension spring or a gas compression spring, which is arranged between the first hinge rod side connection point (16) and the second body-side connection point (20). According to the invention, the first hinge rod side connection point (16) of the spring element (14) of the force element (14) can be moved so that the closing torque is increased and the flap (4) closes.

Abstract

The invention relates to a method and a device for removing a film, in particular a protective film (4), adhering to an essentially flat surface of a plate-like support or adhering to a flat, flexible base film (1) due to adhesion and/or electrostatic charge. The protective film is lifted off of the support or base film by way of a height-adjustable pressure application element (8) comprising an adhesive layer or a self-adhering strip (9). The plate-like support, which is sized to a specific further processing size, or the base film or a multi-layered film arrangement is held at least at the front area on a support table by way of a vacuum suction device (3). After the protective film is raised, it is grasped by a gripper from behind at a removal device that is moveable relative to the support table and is pressed against a back support (6) at the removal device, said film being removed by moving the removal device and suctioned by a suction device.
